SPECIFICATION forming part of Letters Patent No. 783,597, dated February 28, 1905.

Application filed May 5, 1904- Serial No. 06,5

To all when), /2 In/(11y concern.-

Be it known that l, JAooB S'ruulmn, a citizen of the United States, residing at Kalamazoo, in the county of Kalamazoo and State of h lichigaii, have invented a new and useful ,lm.- proven'ient in a Globe-Valve, of which the following is a specilication. I

This invention relates generally to globevalves, and more particularlay to certain improvements therein, whereby the valve is made self-grinding upon its seat and also by means of which the walve-s 'iiiulle can be quickly and .easily attached to the threaded stem which raises and lowers said valve.

The invention consists in the novel features of construction hereinafter fully described, and pointed out in the claims.

In the drawings forming a part of this specilication, Figure 1 is a vertical sectional view of a globe valve constructed in accordance with my invention. Fig. 2 is a detail perspective view of the valve and its spindle. Fig. 3 is a detail view showing the lower end of the stem. Fig. 4 is an inverted bottom plan view of the same. Fig. 5 is a sectional view on the line 5 5 of Fig. 1, and Fig. (5 shows the key and wedge in detail.

, In carrying out my invention I employ a body portion A, which is provided with the usual threaded ends A and the threaded neck A", into which screws the bonnet B, said bonnet being provided with the usual construction of gasketa'iut (J. 1) indicates the subdivid ing diaphragm or partition arranged with in the body and having the circular horizontal opening l) surrounded by the irusto-conical ring 1), which forms the seat for the valve E, the lower face of said valve being recessed, thereby providing a downwarilly-extending circular flange E, which overlaps the truste conical ring D and seats thereon, the lower face of the valve resting upon the top 01 said conical-ring seat, as most clearly shown in Fig. l. The valve is provided with an integral spindle E which iits into the externallythreaded stem l provided with a hand-wheel '1 at its upper end, said stem working in. the

threads carried by the bonnet tor the purpose of raising and lowering the valve. The spindle E is smooth and the bore in which it lits is also smooth, and in order to connect the spindle and stem I provide a recess ("r in the side of the spindle adjacent its lower end and into which fits a key lrl, said key being oi a thickness greater than the depth oi the recess, so that it projects beyond the face oi the spindle and is adapted to lit into an interior re cess 1 produced in the stem adjacent its lower end, said recess 1 being slightly wider than the key H, for a purpose hereinafter explaineril. At the lower end oi? the stem is produced a transfer dovetailed recess K, into which lits a wedge L, said wedge litting beneath thelower end of the key H, as most clearly shown, thereby securely connecting the spindle and stem together, so that when the spindle is raised and lowered the valve is also raised and lowered, and by having the recess 1 slightly wider than the key H a limited amount ol play is had. between the parts.

.l'laving thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The combination with a valve-seat, ot a valve adapted to cooperate with the said seat, and having an integral stem, said stein being recessed on one side, an adjustable stem having a longitudinal and a transverse recess, said recesses eoinmunicating, said adjustalde stem litting over the integral stem, a key litting in the longitudinal recess of thead'justable stem, and in the recess of the valve-stem, and a wedge fitting in the transverse recess 01 the adjustable stem.

52. The combination with a body having an apertured partition, of a lrusto-conical valveseatsurrounding said aperture, a valve having a flange adapted to engage said valve-seat, a recessed spindle integral with the valve, a hollow rotatable, and vertically-inovable stem adapted to lit over the spindle, said stem being transversely recessed adjacent its lower end and having a communicating lol'igitudinal recess adapted to register with the recess ol the spindle, a key adapted to rest in the two last-lnemiioned recesses, and a wedge adapted to lit the transverse recess 01'' the stem.
